WebHowever, interpreting the curve fitting characteristics of a hyperelastic model is a challenging task. Here, we present an approach to compare different hyperelastic models based on the Maclaurin series expansion of the Cauchy stress. Ogden model and reduced polynomial (RP) model, with same number of material constants were used for modeling. WebSimulating a hyperelastic material requires extra effort as they undergo a very large deformation, sometimes exceeding 800% of strain value. You can minimize these extra …
